This invention relates to a rug or Carpet cleaning machine. K

The. principal object of the invention 1s to provide a machine. whichthroughoutis automatically controlled, so that it will clean a rug,vcarpet or the. like, after the latter is properly mounted inthemachine, with practically no attention until the cleaning process iscompleted. This automatic characteristic ofthe machine applies to allparts thereof including. means for beating a rug or carpet, the meansfor suction cleaning it, the meansfor scrubbing it, and the means for.steaming it. The arrangement also is such that any of these separatemeans may be disused or rendered inoperative when desired in thetreatment of the rug or carpet.

This machineA clean-s onezone or strip of a rub or carpet during onecycle of movement of a rub in -the machine, that is, during themovementgof the rug in one direction through the machine and the reversemovement thereof. Then the machine automatically shifts the cleaningmeans to another Zone and the process is continued until all zones orstrips of the rug have been cleaned and then the machine stopsautomatically.

Such a. machine materially reduces the labor required in cleaning rugs,as one man could operate ten machines if desired, for no attention isgiven to the operation of any machine until the rug is cleaned.Furthermore, it is unusually economical in Hoor space because it is anupright machine so that the -width of the machine is only three or fourfeet.

It requires a very short time, approximately eight minutes, to clean a 9ft. 12 tt. rug. The only labor consists in placing the rug in themachine and taking it out.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims:

In the drawings Fig. 1 is a front elevation ofthe machine with anintermediate por-` tion from top to bottom being broken away. Fig. 2 isaside elevation of the left hand lend of the machine as shown in Fig. 1.Fig. 3 is an elevation of the right hand end of the machine as shown inFig. 1. Fig. 4 is a vertical section taken on the line 4 4 of Fig. 1showing a beater attachment connected therewith. Fig. 5 is the same asthe left hand part-of Fig. 1 showing the scrubbing attachment partlybroken away, and the cleaning fluid tank connected therewith, theremainder of the machine being broken away. Fig. 6 is a vertical sectionon the line 6*(5 of Fig. 5. Fig. 7 is a rear elevation of the beatingattachment, which is shown in side elevation in Fig. 4. Fig. 8 is a rearelevation on avlarger scale of the mechanism at the left hand end ofFig. 5, the remainder of the machine being broken away. Fig. 9 is asection on the line 9 9 of Fig. 8. Fig. 10 is a horizontal section onthe line 10--10 of Fig. 3 showing the steaming attachment. Fig. 11 is afront elevation of what is shown in Fig. 10. Fig. 12 is a longitudinalsection through the left'hand end of the steaming pipe on a large scaleand showing means for regulating the width of the steam line. Fig. 13 isa side elevation of the upper part of Fig. 8 with some parts omitted inorder to make the remaining parts more clear.

The main frame, which is stationary, consists of an upright 10 at theleft hand end of the machine and anupright 11 at the other end of themachine, said uprights being angle irons. and three tubular brace bars12, 13 and 14. Said uprights l() and 11 are mounted in connection withfoot pieces 16 at each end as shown in Figs. 2 and 3 and the frame ismaintained upright by diagonal braces 15 extending between the uprightsand the base bars or foot pieces 16.

In said frame, top and bottom rolls 20 and 21 are mounted on shafts 22in suitable bearings 23 at each end of the frame. carpet with a worm 29in turn driven through a shaft of an electric motor 31. The motor 31 ismounted on a bracket 32 secured to and between the frame bars 19 and 98at the left hand end of Fig. 1. Each of the gears 24 is clutched to itsrespective shaft 22 by means of a clutch 38 of a well known form. Whenthe upper clutch 38 is engaged the roll 20 is rotated to wrap the rugthereon. When the lower clutch 38 is engaged the lower roll 21 isrotated in the opposite direction to wrapv the rugV upon that roll.

The means for controlling the roll-driving clutches includes the handlever 33 vat the right hand end of the machine as shown in Fig. 1 andthe lever 233 at the left hand side, shown in Figs. 1 and 2. The lever33 is fulcrumed at its lower end to the bracket 34 and said lever ispivotally connected with a sh1fting rod 35 extending through the tubularbrace 13 to the other end of the machine. The rod 35 is connected withthe clutch-shifting bar 36 which is fulcrumed between its ends at 37.Said fulcrum is located between the rolls 20 and 21 so that said bar 36will operate to engage one clutch 38 and simultaneously release theopposite clutch 38 so that the rug may be selectively rolled upon eitherroll. The lever 233 is connected to the bar 36 by means of a bar 122,bell crank 125 and link 127. Thus the roll-driving clutches may beoperated either by lever 33 or lever 233 from either end of the machine.

The lever 233 extends forward from the machine as seen in Fig. 2, and isfulcrumed at 39 on arm 139 secured to the upright 10 of the frame, andsaid lever 233 between its ends engages the bar 122 so that when the endof hand lever 233 is moved down, as in Fig. 2, it will operate clutchlever 36 and release one roll clutch 38 and move the other intoclutching position, that is, changev the clutches 38 from the positionsshown in Figs. 1 and 5 to the position shown in Fig. 8, or the reverse.This will reverse the vertical movement of the rug. When the clutchesare as shown in Figs. 1 and 5, the lower roll will operate to wind therug downward and when the clutches are as in Fig. 8 the upper roll willoperate and wind the rug upward.

In order to place the rug 40 into the machine to be cleaned, it isplaced on the floor in front of the machine, one end is lifted up byhand and clamped in a series of clamps 41 secured on a horizontal metalstrip 42 which is supported by straps 43 made of fabric or leather inturn secured on the upper roll 20. The straps 43 have a length somewhatgreater than the circumference of the rolls to which they are secured.Then the machine is started by operating either hand lever 33 or 233 andthe rug or carpet is rolled upon the upper roll. The free end of therug, which is then hanging downward, is likewise secured to a similarset of clamps 41 on similar horizontal metal strips 42 mounted inconnection with the lower roll 21 by a similar set of straps 43.

The rug is made taut or put under tension by means hereafter explained.

If the rug has been used in a clean town or neighborhood or situation,it can be cleaned by the use of the vacuum means or nozzle as shown inFig. 1, without the necessity of beating or scrubbing. To that end,there is provided a vacuum nozzle supported at each end by a bar 51 towhich it is pivotally mounted and the same suspended from a carriage 52which is slidably mounted on the brace tube 12 serving as a bar or thelike of the frame, as shown, so that the vacuum nozzle may slidelongitudinally of the machine and the vacuum nozzle put in engagementwith the surface of the rug. The side elevation shown in Fig. 4 willgive a better understanding of the foregoing construction. As thereshown, when the rug holding rolls 2O and 21 move the rug when vertical,the cleaning means is, by gravity, maintained in engagement with theface of the rug. There we see a suction tube 53 which may be either asingle or branch suction tube leading from a main suction tube 54 shownin Figs. 1 and 2 which is connected with the upper end of a vacuum tank55, see Fig. 2. The air is exhausted from the upper end of the vacuumtank 55 by an exhaust pipe 56 running through a vacuum pump 57 and outthrough a discharge pipe 58. The vacuum pump 57 is driven by a belt 59running from a motor 60.

In the upper end of the tank 55 there is a baiie plate 61 extending downa short distance from the top of the tank and located between the intakeand the exhaust so that the incoming air is deflected downward forfacilitating the separation of the dust, dirt and other heavier foreignparticles therefrom. Such foreign matter drops down on the bottom 155 ofthe tank and may be removed by a lclean-out door 62. Thus no foreignmatter will pass therethrough to damage the vacuum pump. The tank 55 issupported by a plurality of legs 63 extending up from the floor 64.

The suction nozzle 50 is not vertically movable but is laterally movableby a carriage on the bar 12 as indicated in Fig. 1. Said carriage may bemoved by hand by operating a crank 66 at the upper right hand corner ofthe machine as shown in Fig. 1, or by a hand wheel 67 at the other uppercorner of the machine. Said crank 66 operates a sprocket wheel 68 thatis mounted'in a bracket 69 secured on the upright 11. The hand wheel 67is also mounted in a bracket 70 from the upright 10 of the frame andturns a sprocket wheel 71. An endless sprocket chain 72 is mounted onsaid sprockets 68 and 71 and maintained in horizontal positionimmediately above the carriage 52 and is operatively connected with thecarriage 52 by a stirrup 73 which extends'upward from the carriage 52and is seemed at its lower end thereto. The upper side of the chain 72.rides on a roller 74 in said stirrup and suitable-means is provided forremovably connecting said stirrup with the chain 72 whereby it can bereadily connected or disconnected or shifted somewhat.

Such means as shown in Fig. 1 consists of a pin 75 extending up from thebottom of the stirrup 73 into the space between the adjacent. ends oflinks, and a tapered key 76 extending through the stirrup and resting onthe link of the chain above said pin. This enables the chain andcarriage 52 to be relatively shifted as desired.

-In the operation of the machine, after a rug has been attached thereto,the suction nozzle carriage 52 is shifted to the left hand end of themachine, preferably by means of the hand wheel 67. The said carriageremains in that position while the rug is automatically wound from oneroll to the other and return and the lefthand strip orv portion of therug is thereby cleaned. The carriage 52 is then automatically shifted ina horizontal direction or transversely of the machine to engage anotherportion or zone of the rug for cleaning. In the new position, the rug isagain wound from one roll to the other and return, after which anothermovement of the carriage 52 takes place. The intermittent movement ofthe carriage is continued until the rug is entirely cleaned.

The mechanism for automatically reversing the direction of rotation ofthe rolls 20 and 21 for winding the rug alternately from one to theother will now be described with special reference to Figs. 8 and 9:

Each of the rolls 20 and 21 is provided with a spring bar 106 (seen inFig. 8) which is normally pressed against the roll when a rug is woundthereon. When the rug is unwound from either roll, the spring barassociated therewith is free to spring outwardly to engage a notch 107in a pull bar 108. Each of said pull bars is pivotally fastened at oneend to a link 257 which is in turn pivoted upon the frame member 10.

Each pull bar 108 is slotted at its opposite end 109 to receive a. bolt110 carried by an irregular shaped lever 111, each of which levers is inturn fulcrumed vupon the frame member 10 at 112. A tension spring 113connects each bar 108 with the corresponding lever 111. When either ofthe bars-108 is moved by the spring 106, the spring 113 bars 114 both ofwhich are ulcrumed upon a block 258 carried upon one end of a lever inturn fulerumed upon frame member 10 at 118. A air of leaf springs 259also fastened upon t e block 258 serve to urge the bars 114 to the rightin Fig. 9 against suitable stops upon the block 258. Each of the bars114 carries a dog 116 which is moved to engage a ratchet wheel 115 whenthe corresponding bar 114 is moved by its lever 111. Each of the ratchetwheels 115 is formed integrally with one of the bevel gears 24 and runsfreely upon its shaft 22 unless the corresponding clutch 38 is inengagement. The said ratchet wheels are therefore continuously rotatedin the direction of the broken arrows in Fig. 9. By this mechanism, whenthe rug has been unwound from the lower roll 21, the lower bar 114 ispressed inwardly against the action of its spring 259 to engage thelower dog 116 with the lower ratchet wheel 115. The bars 114 are therebypushed upwardly and the leverv85 is rocked in a counter-clockwisedirection. Similarly, when the rug has been unwound from the upper roll20, the lever 85 is rocked in a clockwise direct-ion.

At the oppositevend of lever 85, a yoke 119 is fastened by means of apin 89 and the said yoke is secured on the upper end of a rod120extending downwardly through an opening in an arm 121. The rod 120 isadjustably held in position upon said arm by adjustable collars 123. Thearm 121 is carried upon a vertical bar 122 slidably mounted upon theframe member '10 by means of guides 124. The lower end of said bar'ispivoted to a bell crank 125, fulcruined upon the upright 10 at 126 andin turn connected by a link 127 to the clutch-shifting lever 36. By thismeans, when the rug has been unwound from the lower roll and the lever85 has been rocked counterclockwise, the shifting lever 36 is moved toengage the lower clutch 38 and disengage the upper clutch 38. Thedirection 4of rotation of the rolls is thereby reversed and the rug isthen wound from the upper to the lower roll. Similarly, when the rug hasbeen unwound from the upper roll, the shifting lever 36 is moved todisengage the lower clutch and to engage the upper clutch.

The mechanism by which the automatic movement of the carriage 52 isperformed will now be described with special reference to Figs. 8, 9 and13:

A bevel gear 168 carried upon a horizontal shaft 250 is continuouslydriven by one of the bevel gears 25 carried by the shaft 26. The shaft250 also carries a sprocket 251 about which is trained a sprocket chain252. The

llt

'When the said clutch members are chain 252 is also trained abouta-sprocket 253 -which forms part of a clutch member 100 are engaged, thechain 72 is, therefore, op-

erated to move the suction nozzle carria le 52.

isengaged the carriage 52 remains stationary.

For shifting the clutch member 100, a shiftin lever 101 is provided. Thesaid lever is fu crumed upon an arm 102 rigidly attached to the upperend of the frame member 10.

A tension spring 104 is attached to one end of the shifting lever 101and its opposite end is attached to an arm 105 carried -upon tliebearing 81. The said spring serves to urge the lever 101 in the properdirection to engage the clutch member 100 with the mating member 254.

A link 103 is pivotally attached to the lever 101 and its opposite endis pivotally connected at 95 to a pair of levers 94 and 96. The lever 94has a free end extending outwardl as shown particularly in Figs. 8 and13. he lever 96 is fulcrumed at 99 upon a frame member 98 and has a freeend p'rojecting inwardly beneath tliesprocket 71. By means of theselevers, the link 103 may be forced downwardly to move lever 101 in theproper direction to disengage the clutch members 100 and 254. v

The lower end of lever 94 terminates in a hook portion adapted to engagean angle member 94a attached to the frame member 10. When the lever 94is moved to engage the said angle member, as shown in Fig. 8, the link103 is moved downwardly and the lever 101 is rocked against the actionof spring 104 to disengage the clutch members 100 and 254. The clutch isthereby locked out of engagement and the carriage 52 remains in astationary position until it is desired to start the machine, at whichtime lever 94 is manually disengaged from the angle member 94a as shownin Fig. 13. When so disengaged, the spring 104 draws the clutch intoengagement and also elevates the free end of lever 96 into the path oftravel of a plurality of lugs 97 carried upon the chain 72. `When one ofsaid lugs engages the lever 96 in the movement of chain 72, the saidlever is depressed sufficiently to disengage the clutch and stop thecarriage but not sufficiently to latch the lower encl'of lever 94beneath the angle 94a. The lugs 97 are properly spaced upon the chain 72to stop the carriage in position for the cleaning of each zone of the'rug. l

A ratchet wheel 83 is fastened upon the shaft 80. The said ratchet wheelis engaged by the p'awl-shaped upper end of a vertical bar 84, the lowerend vof which is pivotally fastened to t-he lever 85 by the pin 89. Thesaid bar 84 extends loosely throu h a stirrup bar 87 near its upper endan is spring pressed toward the ratchet wheel 83vby a torsion spring 88coiled about the pin 89 and having an upwardly-extending portionengaging said bar.

At the end of each complete movement of the rug upon the rollers, thebar 84 is vertically reciprocated by the rocking of the lever 85previously described. Each reciprocation of the said bar moves theratchet wheel and shaft 80 vthrou h a distance represented by 'one toothof t e said ratchet wheel. This movement of the shaft 80 is effective tomove the lug 97 away from the end of the lever 96. When the lug 97 is somoved, the spring 104 is free to draw the clutch into engagement and thechain 72 is moved a suflicient distance to bring the next of the lugs 97into engagement with the lever 96. Thereupon, the said lever is againactuated to disengage the clutch. By this meansthe carriage 52 remainsstationary at each of predetermined positions until the rug has beenwound from one roller to the other and return and, at the end of eachwinding operation, the movement of the carriage4 to its nextpredetermined position is automatically actuated. By a suitable choiceof the size of theteeth of ratchet 83 and the length of travel of thevertical bar 84, the machine may be adjusted so that the rug may b ewound from one roll to the other several tlmes at each of thepredetermined positions of the carriage 52 if desired.

When the carriage 52 reaches the extreme right hand end `of the machine,it engages a stop member 255, shown in Fig. 1, whlch is carried upon ahorizontal rod 91. The opposite end of said rod is supported upon theupper endof the frame member 10 as shown 1n Fig. 8 and carries an arm 92in turn carrymg a link 93 which is attached to the lower portion of thelever 94.

The movement of the rod 91, upon engagement of the carriage 52 withthestop member 255, therefore, moves the lever 94 from the position shownin Fig. 13 to that shown in Fig. 8, thereby disengagin the clutchmembers and 254 and latcglriing the lever 94 beneath angle 94a toprevent further movement of the carriage. At the same time, a dog 90carried by rod 91 engages the verti-I cal'bar 84 and moves the sameagainst the action of the spring 88 out of engagement with the teeth ofratchet wheel 83. Thus, when the carriage 52 reaches the extreme righthand limit of travel, the clutch and the `bar 84 are both renderedinoperative to move it further. The same result may be accomplishedmanually at any desired point in the operation by means of a lever 256attached to the rod 91 and the frame member 11 as shown in Fig. 1.

VEach roll 20 and 21, when idle, is held taut by a friction brake asseen in the right hand end of Fig. 1. There is shown on the ends of thetwo rolls 2O and 21 a collar 133 which serves as a brake band and isengaged by the brake shoe-13.4 which is controlled by a lever 135 shownin Fig. 3 thatis actuated by a connecting bar 136 in Fig. 1 to a b'ellcrank lever 137 and link 138 from the hand lever 33. When the lever 135is in the position shown in Fig. 3, the upper brake shoe 134 is set and.

the lower brake shoe 134 is released. The lever135 is connected with thebrake shoes by a tube 140 into which a rod 141 is slidable and it isspring-pressed outward bya spring 142 which is properly connected withthe brake shoe 134 as seen in Fig. 3.

rPhe cleaning nozzle is short compared with the horizontal dimensions ofthe rug so that while the cleaner remains stationary and in engagementwith the face of the rug it will clean one zone or strip during a roundtripmovement of the rug and then the cleaner is moved in position toclean the adjacent strip or zone of the rug during its next roundtrip ormovement.

. The beater carriage is illustrated in Figs. 4 and 7 and consists of aframe formed of upi rights 145, cross bars 146 and diagonal braces 147.It is mounted on sheaves 148 that'travel on the tubular brace 13 as seenin Figs. 1 and 4. The upper parts of the bars 145 are bent horizontallyas shown in Fig. 6 vand are secured to the underside of the carriage '52heretofore described. Uponl the horizontal portion of said bars 145,plate 150 is secured, which supports an electric motor 151. Power istaken from the motor through a belt 152 to a pulley 153 which drives ashaft 154 on which is mounted a pair of cams 155. As said cams revolvein the direction indicated by arrows in Figs. 4 and 6, they strikefingers 156 secured on hollow tubes or shafts 157 that are held in a barsupport 158. Said iingers 156 are rigidly connected with beaters 160,which are loop-shaped as shown in Fig.

7, and are adapted to engage and beat the rear side of the rug directlyopposite the slot in the suction nozzle 50 seen in Fig. 4. The beatersare forced against the rug by means of springs 159 secured thereto andanchored to the heater carriage, the cams 155 serving to move the beateraway from the rug. Beaters 160 are held in idle position by hooks 161,as shown in Figs. 6 and'7. The two beaters illustrated are mounted onindependent shafts and may be adjusted to beat alternately orsimult-aneously by adjusting the position of cams 155.

The scrubbing means is illustrated in Figs.

5 and 6 Where there is shown a scrubbing brush 165 extendinglongitudinally of the machine and which engages the rug 40. Itl

is mounted at each end in a bracket 166 and is reciprocated by aconnecting bar 167 shown in Fig. 5 which is pivoted eccentrically to abevelled gear 168 driven by the pinion 25.

The scrubbing brush 165 is supplied with soapy water or the like from atank V170 through a hose 171 and a pipe 172, from which the cleansingfluid trickles onto the bristles of the scrubbing brush. Suitable meansfor supporting said tank 170 is provided but 'it is not shown herewith.The cleansing iuid drips or drains down into a drain trough 173 whichrests on the floor. When the scrubbing brush 165 is not used, it islifted up oif the brackets 165 shown in Fig. 6 and folded down out ofthe way by means of a bar 174 which is secured to the brush member 165and which, at its lower end, is pivoted to a link bar 175 that ispivoted to the supporting tube 13. 1

After the rug has been beaten and scrubbed, it is steamed by the meansshown in Figs. 3, 10 and 12. Steam comes from a boiler room, not shown,through a pipe 180, see Fig. 1, and it is controlled by a hand valve181. The steam passes into a steam'tube 182 that eX- tends the fulllength of the machine and is provided throughout its length withperforations-183 for the escape of the steam to the rug. The steam isadmitted into the right hand end of the tube 182, as shown in Fig. 10,and the other end of said tube is closed.

The right 'hand end of the tube 182 screws into a head 184 as shown inFig. 11.V yA steam pipe connection 186 leads from the valve 181 andcarries steam which it introduces into the tube 182. The pipe connection186 is mounted in a swivel connection 187 which extends through abracket 188 and has secured on it a handle 189, whereby the steam tubecan be elevated into the horizontal position for use and be held in thatposition by a leaf spring 190 shown in Fig. 3, or the tube 182 can beturned down out of the way. A head 185 at the left hand end of the tube182 is pivoted at 191 so as to cause both ends of the tube to swing downor up as the lever 189 may be operated.

The steamer is positioned as in use in Fig. 3. Means is provided forregulating the width of rug surface that it steams as illustratedparticularly in Fig. 12. In each end of the steam tube 182, there ismounted a long tapered sleeve valve 193 which is tubular at the outerend. The valves 193 extend for some distance into the tube 182 and theirv secured a handle 196. The valve 193 at the right hand end of the tube182, is secured on a head 197 that is similar to the head 194: exceptingthat it is perforated to admit steam and it-.is operated by a similarhand lever 196 and shaft 195. When the valves 193 are located as shownin Fig. 12, the tube 182 wouldsteam for about one-half its length, butif the valves were turned so as to open all the ports 183, the steamwould operate throughout the entire length of the tube 182, as shown inFig. 11.
